Patented May 28, 1935 PATENT OFFICE 2,003,224 CONTAINER Edwin J. Sohoettle, Philadelphia, Pa, assignor to Edwin J. Schoettle Company, Philadelphia, Pa., a corporation of Pennsylvania Application August 2, 1934, Serial No. 738,123

4 Claims.

This invention relates to containers formed cardboard or similar material and more particularly to that type of container which is constrncted of several pieces of material connected together in the process of forming the container.

important object of the invention is to provide a joint or look between these sections formed from the material of the sections and readily assembled, which, by means of a single connection, securely locks the sections against relative movement in all directions.

A further and more specific object of the in vention is the provision of a slip and tab connection between the container sections of this character or between any two similar sections which it may be desired to connect, which provides a multiplicity of shoulder ahutments be tween the sections so arranged. that they resist relative movement of the sections in any direction.

These and other objects, I attain by the construction shown in the accompanying drawing,

wherein Fig. 1 is a fragmentary prospective view of the container, the lid and body of which are formed of two separate sections connected in accordance with my invention;

Fig. 2 is an enlarged sectional View on line 2-2 of Fig. 1;

Fig. 3 is a plan view of one of the sections showing the joint element formed therein; and

Fig. 4 is a plan view of the other section showing the joint section formed-therein.

Referring now more particularly to the drawing, of the elements A and B, which which are to be connected, the element A is formed with an opening ill, the material of which may be either removed or left in the form of a flap F as illustrated in the present instance. The form of the opening may be varied as desired but must provide corners l l spaced transversely of the sheet and wall portions l3 which are spaced longitudinally of the sheet from a line connecting the corners H and are more or less opposed to one another in a direction-transverse to the sheet.

The section B is formed with a shallow tab it providing shoulders I5 facing away from one another transversely of the sheet and adapted to engage at the junction of the margins of the tab, with the section B against the wall portions 53 and is formed with a second tab means it embodying the shoulders ll facing away from one another transversely of the sheet and adapted to engage in the corners ii of opening it.

Tab means it may be either unitary or in the form of two distinct tabs asdesired and in the assembly of the sections, the shoulders H, which are provided thereby, are first engaged in the corners ii of opening it. It may be 5 here pointed out that the flap F is left attached as herein shown, it will assist in guiding the shoulders 51 to their proper location, particularly if the walls is are divergent as herein illustrated. 'Ihis ilap will also serve to reinforce the tab means it against inward flexing. When the shoulders I! are properly seated in the corners, the flap M, which has its lower terminal with at least one point spaced a greater distance longitudinally of the sheet from the adjacent ends of the shoulders ll than the now opposed portion of opening ill, is forcedover the edge or" th opening so that the junction of the shoulders ill with the section B will'engage against the opposed walls l3 and shoulders I! will overlap the edge of the opening ill.

It will be seen from an inspection of Fig. 1 that longitudinal pressure downwardly upon the section 3 adjacent the upper edge of the secticn will be resisted by engagement of the shoulders 55 with the lower wall of the opening and similarly an upward pull at this point will be resised by the engagement of the shoulders it against the upper wall of the opening at the corners ii. Any attempt to rotate the section B with relation to the section A will be resisted by one or the other of the shoulders l5 and the diagonally opposed shoulder H so that a complete locking connection of the two sections is provided. While tab M. is disclosed as formed at the lower marginal edge of the section, t might obviously be formed inwardly of such edge if so desired.

Since the construction is capable of considarable modification without in any manner departing from the spirit of my invention, I do not wish to be understood as limiting myself thereto except as hereinafter claimed.

I claim:

1. Connected sections of a cardboard container or the like wherein one section has an opening affording transversely spaced opposed corners and transversely spaced walls opposing one another at a point spaced longitudinally of the section from said corners, the other section having tab means afiording shoulders transversely spaced thereon a distance equal to the distance between said corners and engaged therein, and a second tab means afiording shoulders spaced transversely of said second section and engaged and fitting between the opposed walls of the opening of the first member, at least a portion of the last-named tab means being spaced longitudinally of the second section from the first-named Shoulders a distance such that it overlaps the confronted edge of the opening of the first section intermediate the points of engagement of the last-named shoulders with said opposed wall portions.

2. Connected sections of a cardboard container or the like wherein one section has an opening afiording transversely spaced opposed corners and transversely spaced walls opposing one another at a point spaced longitudinally of the section from said corners, the other section having tab means affording shoulders transversely spaced thereon a distance equal to the distance between said corners and engaged therein, and a second tab means affording shoulders spaced transversely of said second section and engaged and fitting between the opposed walls of the opening of the first member.

3. Connected sections of a cardboard container or the like wherein one section has an openin afiording transversely spaced opposed corners and transversely spaced walls opposing one another at a point spaced longitudinally of the section from said corners, the other section having tab means afiording shoulders transversely spaced thereon a distance equal to the distance between said corners and engaged therein, and a second tab means afiording shoulders spaced transversely of said second section and engaged and fitting between the opposed walls of the opening of the first member, said opposed walls being convergent and the material freed in forming the opening being left attached to the first-named section between said corners.

4. Connected sections of a cardboard container or the like wherein one section has an opening affording transversely spaced opposed corners and transversely spaced walls opposing one another at a point spaced longitudinally of the section from said corners, the other section having tab means affording shoulders transversely spaced thereon a distance equal to the distance between said corners and engaged therein, a second tab means affording shoulders spaced transversely of said second section and engaged and fitting between the opposed walls of the opening of the first member, and means on the first section reinforcing the first-named tab means to prevent displacement thereof through the opening between the said corners.
